G Grades

General Application Grades – G Grades

By applying cold isostatic pressing manufacturing technology, which we have developed over many years, Tokai can now offer ‘G’ series Isotropic graphite entirely suitable for today’s most advanced applications. A range of graphite grades for use in both high temperature and mechanical applications that have been developed to suit the demanding needs of todays industrial processes. With the ‘G’ range of graphite, Tokai Carbon meets the requirements of the continuous casting, glass, semi-conductor & photovoltaic, aluminium de-gassing/casting and hot pressing industries.
